Hello.
I am new here on the site, but I hope to meet experienced users that can help me a little further.
It is about a Lorch V 24 AC/DC Tig welder.
The machine is about 13 years old, and I have had it from brand new. It has always been located in a dry, warm room and it has been very stable throughout the years. Only once it has burned one of the two small glass fuses on the small circuit board on the right side, the same side where the primary power connection and main switch are located.
It has shown a few error codes on the water cooling a few times, but not something that has been a problem in terms of the machine's function and welding abilities.
Over time it has developed a little trouble turning on the HF arc when over 200 A in AC mode. And the latest problem is now that it cannot turn on the arc in AC or DC mode at all. However, I could scratch the tungsten on the subject and start the arc that way.
I know that the dealer who sold the machine here in Denmark no longer exists, and that there are no other dealers of Lorch Welding Machines in Denmark. Therefore, I have had a technician from Migatronic to try and fix this specific problem.
The technician has replaced two out of 3 circuit boards + 1 AC module (left side, opposite side of the glass fuses). Then it could draw an HF arc, but the sound was the same as by AC in both AC and DC mode, and it could still not weld properly.
He has now given up on fixing the error, and I have asked him to put back the old circuit boards and AC module into the machine.
The technician told me that the two circuit boards were “exchange circuit boards” from the Lorch factory. But I must say that it seemed a little strange, because he still had the old circuit board?
As I described earlier, I cannot find anyone in Denmark that can help me bringing my machine back to normal condition.
Maybe there are someone in here who can give me some advice?
Sincerely, Møjchris.
